Estimate axial column load, tributary area load, dead load, live load, roof load, column self weight, bearing pressure, slenderness ratio, Euler buckling load, and simplified column utilization. Use this column load calculator for wood posts, steel columns, concrete columns, deck posts, basement columns, porch posts, and preliminary structural planning.
Tributary load:
The calculator multiplies tributary area by dead, live, roof, or snow load to estimate load carried by the column.
Axial load:
The calculator adds tributary load, beam reaction, point load, and column self weight to estimate total axial load.
Compression check:
The calculator divides axial load by column area and compares it to the entered allowable compression value.
Buckling and bearing:
The calculator estimates slenderness, Euler buckling load, bearing pressure, and simplified utilization.
A column load calculator helps estimate the vertical load on a column, post, or support before checking size, bearing, and footing requirements.
It can help compare tributary area, axial load, compression stress, bearing pressure, slenderness ratio, buckling load, and approximate utilization.
Your result shows estimated tributary area, area load, tributary load, added beam reaction, point load, column self weight, total axial load, compression stress, allowable compression, slenderness ratio, Euler buckling estimate, bearing pressure, and utilization checks. These are planning estimates only.
Column load is the vertical axial load carried by a column, post, or support. It can include floor loads, roof loads, beam reactions, point loads, and the column’s own weight.
Find the tributary area supported by the column, multiply it by the design load in PSF, then add beam reactions, point loads, and self weight.
Column slenderness compares unsupported height to radius of gyration. Slender columns are more likely to buckle and may have lower allowable capacity.
No. Final column design should follow local code, material standards, connection details, bracing conditions, eccentricity, buckling rules, footing design, and professional engineering when required.
